Over its history, the territory of present-day Latvia has been occupied or settled on by people from many foreign countries. This podcast tells the story of these past invaders and the castles, and other monuments, that they built. I visit the Occupation Museum in Riga. I tell the story of the Minox spy camera. I tell the tales of two castles, including a ghostly visitor and the possible Latvian origins of the Crocodile Dundee film.
